You can use decrypt9 and make a back up of your agbsav.bin if you don't want to lose your saves. Then do everything for a9lh and then use decrypt9 to reinsert your saves. If you don't want to lose game progress.

EDIT: Though, I assume that your gba games are also on emunand, so your don't need to reinstall them.

Nope, just do the prep work that needs to be done and skip the downgrading since you are all ready on 9.2. So Section I and III are your focus.

It seems that @Sykoh is reading the older guide. There's a new one using Decrypt9 to inject a CTRNAND already in 2.1.0.@Sykoh, try reading the new guide from here: https://github.com/Plailect/Guide/wiki/Homebrew-Launcher-(Browser)
Since you already use *hax and CFW you can try using Decrypt9 directly from homebrew launcher.
Using Decrypt9 you will want to do a backup of your emunand partition and restore it at the end of the guide instead of restoring your sysnand backup (but I strongly recommend that you do both backups in the case that you ever want to restore a clean sysNAND back).
You won't need to format your SD card if you want to continue using emuNAND for whatever purpose, but if you want to format it to reclaim the space used by emunand partition (using SDFormatter with size adjustment on or emunand9 format options) you have to backup your Nintendo 3DS folder and copy it back after formatting.

Some pages from the Wiki seems to be outdated yet. On a guick navigation that I've done right now I've found some "side guides" pointing to the older version of the guide.
But you may start from the link that I gave you previously since you already use CFW.

Yeah, OP's quoted text from the guide was taken directly from the new one. I've read the old one so much, its like ingrained in my brain now. Haha.

BUT, it is much clearer what you should do if you are already on 9.0-9.2 from the link you provided. The no browser way has it worded a bit confusingly, should be amended. Hope you have been able to carry on and get it done, OP.

And don't forget to make a back up of your gba saves using decrypt9 before you write emunand to sysnand.
